Filed: 1993-09-21
Abstract: PURPOSE:To prevent axial enlargement by forming the cylinder body of a double fluid pressure cylinder device into double-cylinder shape forming an annular cylinder chamber, and forming also a piston into double-cylinder shape. CONSTITUTION:In the case of removing a cutting tool fitted to a spindle, operating oil is supplied to a second oil chamber 33 through an oil groove 31 and a communicating hole 29 to move a first piston forward so that a sleeve 12 is pressed forward against a plate spring group 13 and separated from the step part 11c of a pressing member 11. Operating oil is supplied to a third oil chamber 37 through a communicating hole 38, and operating oil in a fourth oil chamber 39 is discharged from a communicating hole 40. A piston 36 is thereby moved forward to press the pressing member 11, thus pressing a tension bar 6. The base part of a collet is thereby pressed by the tip of the tension bar 6, and the collet is placed in the open state to release the grip of the cutting tool. At the same time, the pull stud of the tapered shank of the cutting tool is pressed to push out the cutting tool.

Abstract: PURPOSE:To prevent a trouble without being attended with costup for an image repeat function by deciding the size of a designated area and varying the method of the sequence control of the copying operation. CONSTITUTION:When the image repeating mode is selected by an operation section and an area desired to be repeated by a digitizer 114 is designated, a control section 111 decides the size of an object area and when the size is larger than a prescribed size, image repeat is applied with the similar operation as the conventional copying operation. When the size is discriminated to be smaller than the prescribed size, the scanner section 1 reads the data by a 1st main scanning in a 1st repeat and a printer section 3 records a picture. Then the scanner section 1 does not read the picture in the 2nd and subsequent repeat processings, a control section 121 records the image of the 1st repeat remaining in a synchronizing memory to control and to record signals PBVE, PVE. When the repeat by one main scanning is finished, the control section 121 carries the recording paper by a prescribed quantity to apply the picture recording by the next main scanning. The operation above is repeated to apply image repeat.

Title: Reinforced type optical fiber cable
Inventor: LOGAN ERIC R
IPC: G02B6/44
Filed: 1999-09-10
Abstract: PROBLEM TO BE SOLVED: To obtain an optical fiber cable excellent in crash resistance. SOLUTION: Adjacent to a tube 13, the optical fiber cable 10 has a strength assembly 30 which imparts excellent crash resistance to the cable. At least one of the strength assembly has strength members 32 which is in contact with the tube housing at least one of the optical fiber 11. The strength member is joined to a first jacket 34 and is surrounded by a tape 36 for armor and a second jacket 38. When crash load is applied to the optical fiber cable, stress generated in the cable is profitably dispersed by the strength assembly and thereby stress concentration and excess deformation of the cable caused by the crash load are avoided.  Since coupling between cable constituting parts of the strength assembly 30 is tight and clearance therebetween is minimum, both or any one of slippage and warpage of the constituting parts being under stress is prevented and thereby the stress is uniformly dispersed and attenuation of transmission light in the optical fiber cable caused by crash is prevented.
